MACHINE FOR DRESSING THREAD.

Specification of Letters Patent No. 30,824, dated December 4, 1860.

To all whom it may concern:

Be it known that we, HEZEKIAI-i CONANT, at present residing atWillimantic, Vindham county, and State of Connecticut, and LAWSON C.Ivns, of Hartford, in the county of I-Iartford, in the same State, haveinvented certain new and useful Improvements in Machinery for the Sizingand Polishing of, Thread or Sewing-Cotton or Similar Articles, and thatthe following specification, taken in connection with the drawings, is afull, clear, and exact description thereof.

In the drawings Figure l is a vertical longitudinal section through themachine in the line X X of Fig. 2. Fig. 2 is a plan or t-op view of themachine, and Fig. 3 is a detail drawing showing in elevation a part ofthe apparatus for giving a transverse motion to the thread being sizedand polished.

I/Ve have been led to these improvements by careful consideration ofmachinery now in use for the purpose of sizing and polishing sewingthread, noticing its defects and its excellencies and having in view theconstruction of a more simple machine less costly to use and keep inrepair and more certain and correct in its action.

In the sizing and polishing of thread by machinery now in use and knownto us there are certain difficulties. The first arising from the factthat diferent parts of long lengths of thread are exposed to differentdegrees of tension during the operation and while wet with size, whichcauses the thread when finished to be of different numbers or ofdifferent degrees of fineness in various parts of its length althoughthe hank or skein of thread before being sized was of equal finenessthroughout. A lsecond difiiculty arises from the use of a number orseries of rapidly revolving brushes, which act on the thread insuccession immediately after it has left the sizing vat and before ithas been dried. The brushes cost a good deal in the first place, takesome power to run them up to speed, and as they are obliged to take upall the moisture from the yarn soon become saturated with wet and mustbe removed and dried and cleansed. Another difficulty arises from theyarn proceeding from the vat directly to the first of the series ofbrushes. Sometimes in spite of wipers or nippers to remove thesuperfluous size too much size is carried along by a certain part of thelength of thread and when this part arrives at the first brush theoverplus of size is flung off by the brush into the air and it oftenfalls on and damages the finished thread. All these defects of themachines in i use and known to us are remedied by our present invention.

In the drawings is represented a strong frame of wood which supports theshafts and various acting parts of the machine and on it is mounted atthe front of the machine a rod DZ extending across the frame and free toslide crosswise in proper guides such as y. This rod may be notched onthe upper side or have extending upward from it small wires or pegsbetween which the various threads to be sized and polished pass; thesethreads are represented in the drawings by red lines. Immediately behindthis sliding rod is a vat or cistern A which is to contain size andextending across this vat is a small rod a which we prefer to make ofglass under which the thread passes; extending also across this vat butabove the surface of the size is another similar rod a upon which reststhe edge of a wiper 0 hung on arms c3 pivoted to two standards one ofwhich. rises from each side of the frame; this wiper by its own weightrests against the rod a. Between these two standards and supported bythem is another rod a2 and pivoted onto the same standards are two otherwipers c o2 the former of which is caused to press downward by a ball orweight fw supported on a rod which passes through a hole in the shaft ofthe wiper. The wiper c2 is caused to press upward by a similar weightL02 and both of the rods on which the weights are supported are capableof being moved through the holes in the shafts so that the force withwhich the wipers are respectively forced downward and upward may beregulated. The edge of the size vat is extended under al1 these wipersso as to receive and save size that may be removed by them. Next inorder along the frame is a series of pipes G Gr. This series extendsacross the frame or nearly so and has proper connectionsfor carrying offcondensed water' and vthrough which the series may be supplied with.steam. Behind this series and supported in proper slotted standards is arod D. Thisrod can be raised and lowered in the slots lo and may besustained at any proper point by pinsor set screws and may if desired beso Vconstructed as to traverse across the frame in the f plainly shownin F ig. 2. Behind this brush passing through slots 7c in otherstandards is a rod D whose ends are slotted as seen in Fig. 3 andthrough these slots pass pins so that the rod may be supported at anydesired height and is still free to slide crosswise of the frame. In oneend of this rod is a pin which is embraced by the slotted end of a leverZ pivoted at s and in the lower end of this lever is another slot intowhich enters a pin g which protrudes from a disk keyed on a shaft Owhich runs lengthwise of the machine, the whole contrivance being suchthat when the shaft revolves the rod D shall be caused totraverse to andfro crosswise of the machine. This rod D should have wires or pinsprojecting from its lower side or it may be notched and the rod D2 isprovided with a similar apparatus by means of which it is also caused tomove sidewise across the machine. Behind this rod D are other standardsin proper journals in which isfsupported a rol er E which we prefer tocover with felt or india-rubber and on the shaft of this roller is abelt pulley S. Immediately above this roller is another E similar to itwhose journals are free to slide up and down in slots in the standards.This roller rests on the former one or on threads passing between thetwo and is moved by friction only.

A belt not shown in the drawings is to pass around the axle of the brushand thence around a pulley M on a shaft N. This shaft carries an endlessscrew which engages `with a worm P on the shaft 0 thus causing thatshaft to revolve slowly when the brush is in motion. Another pulley K2is supported on the shaft N and around this latter pulley a belt is tobe placed which also surrounds the pulley S so that the roller E willalso revolve when the brush revolves but at a much lower rate of speed.The relative velocities of the brush the take up roller E and thetraversing rods may be varied as necessity requires 1n any propermanner.

The rods D D are adjustable as to their height in order to determine howmuch of the circumference of the brushthe threads shall pass over. Theroller E is 'free to slide up and down so as to accommodate its positionto varying numbers of thread. The weights on the wipers are adjustableso that greater or less force may be brought to bear to lay the bers andto produce tension v on the thread and the acting surfaces of the wipersare best made of felt or some similar material let into a sort of stockas plainly shown in the drawings thus affording facilworks is to bewound on proper spools which are then to be placed in an ordinary frameso that each spool is fre-e to turn, the threads from a number of thesespools are then to be led over the rod D2 under the rod a between therod a and its nipping wiper 0 thence over the rod a2 between the wipersc c2 over the heating pipes under the bar D over the brush, under D,over the roller E', between it and E, then under Efand thence to spoolsarranged in a frame and caused to revolve by friction so -that eachspoolcan only take up the thread as fast as it is delivered by therollers E E. Steam is now to be supplied to the heating pipes, the sizebox is to be supplied with size, and motion is to be given to the brushand consequently to the other parts connected therewith. The thread willthen pass as shown in the red lines, be saturated with size in the Vat,have the surplus size removed by the first nipperc acting against therod a at whichtime the liber will be partially laid, and then receive asecond nip between 0" and c2 when the fiber will be laid down close,when all superiiuous size will be removed and the thread pinched so hardas'to cause it to move over the brush under sufficient tension. As thethread goes over the pipes the size will be nearly dried, sufficientlyso as to fit it properly for the action of the brush, which will polishthe thread as it passes over it.

The thread is drawn over the brush by the take up rollers which take upconstantly, or equal lengths in equal numbers of revolutions, and whenthe thread leaves them it will be so dry that it can not be stretchedand consequently reduced in 'diameter even though the bobbins to whichit then passes and on which it is wound should at times tend to take upmore rapidly than at others.

During all these operations the thread will by the rods D and D2 (and Dalso if tted properly) be forced to move slowly crosswise of the machineand then back again, thus bringing into action all parts of the surfaceof the nippers and brush causing them to wear equally, giving theirsurfaces time to dry and preventing the difliculties hereinbeforepointed out. And it will be noticed further that owing to the use of thetake up rollers the thread will remain under equal tension until dried,consequently its diameter will not vary in different parts of the samehank; and it will also be observed that owing to the Vlocation of thesteam apparatus between the vat and the brush that thin size may be usedwhich saturates more equally and also that the size will be dry ornearly so when the threads reach the brush, thus doing away with thenecessity of a series of brushes and preventing the brush from throwingsize about the room.

IVe state that we are aware of the fact that a size vat, nippers, areciprocating brush, and a drying apparatus have been used incombination in a machine for dressing warps, arranged in such order thatthe drying apparatus acts after f the warp threads have been brushed;but this apparatus would not answer our purpose for two reasons firstbecause a reciprocating brush is practically useless for polishingthread and second for the reason that in polishing thread it isimportant to dry it before it is subjected to the action of thepolishing brush or brushes. l/Ve therefore do not claim such anapparatus but Having thus described our improved machine for sizing andpolishing thread we claim as of our own inventionl. In combination witha size vat, swinging wipers for making tension and laying fibersubstantially such as described and this we also claim when the wipersare fitted with adjustable weights substantially as specified.

2. In combination with a size vat and a rapidly rotating brush andnippers or any proper device for preventing the too rapid withdrawal'ofthread a constant take up motion consisting of friction rollers or theirequivalents from which thread passes onto bobbins or their equivalentssubstantially as speciied for the purpose set forth.

3. In combination when arranged in the order herein described, first, avat for size; second, nippers or wipers or their equivalents forremoving surplus size and laying liber; third, a steam apparatus or anyequivalent thereof for the purpose of drying size and, fourth, a rapidlyrevolving brush all acting in combination under a mode of operationsubstantially such as is described, and these four elements or parts ofa whole apparatus arranged in the order as described, in combinationwith a traverse apparatus and a constant take up or either of them.

In testimony whereof we have hereunto i subscribed our names in the townof Hartford on this 31st day of October A. D. 1859.
